Abstract
The utility model provides a semi -mounted road train four wheel steering control system, this system include actual semi -mounted road train state detection device, control function module, actuating mechanism, tractor rear wheel steering mechanism, semi -mounted road train state detection device detects the real -time signal that semi -mounted road train travel, and the size of the tractor rear wheel corner of needs is extrapolated to the control function module, and actuating mechanism provides tractor rear wheel corner required power, and tractor rear wheel steering mechanism controls the size of tractor rear wheel corner, the utility model discloses rational in infrastructure, easy operation can guarantee the security of traveling when the high -speed big corner of semi -mounted road train turns to.
Description
Technical field
The utility model relates to semi-trailer train course changing control technical field, especially relates to the management system of a kind of semi-trailer train tractor truck front and back wheel equal energy active steering.
Background technology
When semi-trailer train travels, tractor truck and superimposed trailer had both formed a moving whole, be there is again the relation of motion mutually by the towing pin on saddle.
During semi-trailer train Turning travel, chaufeur is applied to the corner on steering handwheel, the front wheel angle of tractor truck is converted to by steering hardware, tractor truck realizes Turning travel, now tractor truck and superimposed trailer produce a relative angle, by the effect of the towing pin on saddle, superimposed trailer is driven to realize Turning travel.
Compare monomer goods carrying vehicle, more easily there is Cross deformation (folding, whipping, side shake, rollover) phenomenon in semi-trailer train, its kinematics shows as the sharply increase of tractor truck sideslip angle, tractor truck yaw velocity, superimposed trailer yaw velocity and tractor truck and superimposed trailer centerlines.
To the semi-trailer train of Cross deformation, ensure that its stability has little effect usually by means of only adjustment tractor truck front wheel angle, if can while adjustment tractor truck front wheel angle, active accommodation tractor truck trailing wheel corner, then can be reached through the object that active steering control technology improves semi-trailer train lateral stability, ensure that the safety traffic of semi-trailer train.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of semi-trailer train four-wheel steering system.
The utility model is by the following technical solutions:
This semi-trailer train four-wheel steering system comprises actual semi-trailer train condition checkout gear, controlling functions module, actuating unit, tractor truck rear-axle steering mechanism.
Described actual semi-trailer train condition checkout gear comprises longitudinal speed sensor, steering wheel angle sensor.
Described controlling functions module is electrically connected with longitudinal speed sensor, steering wheel angle sensor.
Described actuating unit is electrically connected with controlling functions module.
Described tractor truck rear-axle steering mechanism and actuating unit are mechanically connected.
The utility model active accommodation tractor truck trailing wheel corner, improve the riding stability of semi-trailer train when turning to greatly at a high speed, effectively can reduce failure probability, avoiding the generation of severe traffic accidents.
The utility model is rational in infrastructure, simple to operate, control accuracy is high.
Accompanying drawing explanation
Fig. 1 is composition of the present utility model and functional block diagram.
Wherein: 1, longitudinal speed sensor, 2, steering wheel angle sensor, 3, actual semi-trailer train condition checkout gear, 4, controlling functions module, 5, actuating unit, 6, tractor truck rear-axle steering mechanism.
Detailed description of the invention
As shown in Figure 1, this semi-trailer train four-wheel steering system comprises actual semi-trailer train condition checkout gear 3, controlling functions module 4, actuating unit 5, tractor truck rear-axle steering mechanism 6.
In the present embodiment, actual semi-trailer train condition checkout gear 3 comprises longitudinal speed sensor 1, steering wheel angle sensor 2.
Controlling functions module 4 is electrically connected with longitudinal speed sensor 1, steering wheel angle sensor 2.Receiving the detection signal that longitudinal speed sensor 1 and steering wheel angle sensor 2 provide, calculating the size of the tractor truck trailing wheel corner that (by the method such as tabling look-up) goes out to need.
Actuating unit 5(is as electrical motor) be electrically connected with controlling functions module 4, accept the electric signal that controlling functions module 4 sends, tractor truck trailing wheel corner required drive is provided.
Tractor truck rear-axle steering mechanism 6 and actuating unit 5 are mechanically connected, and accept the power that actuating unit 5 provides, and control the size of tractor truck trailing wheel corner.
